Overview
The AP2161DSG-13 is a single-channel high-side power switch IC designed for USB 2.0 power distribution applications. Manufactured by Diodes Incorporated, it operates within a supply voltage range of 2.7 V to 5.5 V. The device supports a continuous output current of 1 A with a fixed current limit of 1.5 A. It features a maximum on-resistance of 115 mOhms and utilizes an SOIC-8 surface-mount package. The component ensures reliable operation across an extended temperature range from -40°C to +85°C.
Feature Summary
- Integrates high-side switching capability for single-channel power distribution.
- Includes built-in fault protection mechanisms such as over-current limiting and thermal shutdown.
- Supports fast switching speeds with defined rise and fall times for efficient power management.
Applications
- USB 2.0 port power switching
- Peripheral power distribution in consumer electronics
- Battery-powered device power management
Procurement Notes
Verify the specific suffix 'DSG-13' corresponds to the SOIC-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure that the ordering part number matches the exact pinout and thermal characteristics required for the target PCB layout design.
Selection Notes
Select this component for applications requiring a single-channel high-side switch with 1 A continuous current capacity. It is suitable for designs operating between 2.7 V and 5.5 V where low on-resistance is critical for efficiency. Consider the SOIC-8 package constraints and the specified thermal operating range when evaluating suitability for space-constrained or high-temperature environments compared to alternative packages.
Part Context
This part belongs to the AP2161 series of USB power switches from Diodes Incorporated. It serves as a high-side switch solution for distributing power to downstream loads. The series is characterized by its integration of protection features and compact packaging options, targeting portable electronics and USB peripheral applications requiring robust power control.
Replacement Considerations
Compatible variants within the same series include AP2161MPG-13 (MSOP-8 EP package) and AP2161WG-7 (SOT-25 package). These alternatives offer identical electrical specifications but differ in physical footprint and thermal performance. Verify pin-to-pin compatibility and thermal dissipation requirements before substituting.
